OBSL1 Activators

OBSL1 Activators are a diverse set of chemical compounds that indirectly enhance the activity of OBSL1 by modulating various signaling pathways or cellular processes. These compounds act on different targets such as IP3 receptors, intracellular calcium, cAMP levels, GSK-3β, PI3K, mTOR, TRPV1, NF-κB, PKA, and CaMKII, inhibiting their activity and thereby, reducing the activation and synthesis of phosphatases that can oppose OBSL1. Some examples include 2-APB and BAPTA-AM that reduce calcium signaling and increase OBSL1 activity by limiting the activation of calcium-dependent phosphatases. Similarly, Theophylline and ZM-241385 manipulate cAMP levels to inhibit phosphatases that oppose OBSL1.

Further, compounds like Indirubin-3'-monoxime, LY294002, and Rapamycin target protein kinases such as GSK-3β, PI3K, and mTOR respectively, preventing the activation and synthesis of phosphatases that can dephosphorylate the substrates of OBSL1. Capsaicin enhances OBSL1 activity by activating calcium-dependent kinases that inhibit phosphatases opposing OBSL1. Sanguinarine and H-89 limit the transcription and phosphorylation of phosphatases, respectively, which can oppose OBSL1, thereby enhancing its function. In addition, Oleuropein, an antioxidant, preserves OBSL1's function by reducing oxidative stress, and KN-62, a CaMKII inhibitor, prevents the activation of phosphatases that can oppose OBSL1.
